摘要(Abstract)：

以普通聚酯切片为原料,利用固相聚合装置对其干燥增黏,制得低含水率、高黏度聚酯切片,再经熔融纺丝制备出一种新型高强度、大伸长涤纶工业丝。采用X射线衍射仪、差示扫描量热仪对其进行了表征,并利用纤维强伸仪测试了纤维的力学性能。结果表明:固相聚合后的切片结晶度高达60%以上,含水率可达0.000 5%以下,特性黏度为1.105 d L/g。以此增黏切片为原料,可生产出纤度为472 dtex,断裂强度≥7.15 c N/dtex,断裂伸长率为23.7%的纤维。由于该产品具有强度高、伸长率大和毛丝数量少的特点,已在水处理的超滤膜支撑材料领域得到了应用。
Using the normal polyester chips as materials, the high viscosity polyester chips are prepared bySSP device, then the chips are melt-spun to prepare a new industrial polyester yarn with high strength andlarge elongation. The performance of chips are analyzed by X-ray diffraction, differential scanning calorime-try. The yarn's properties are analyzed by fiber strength measurement. The results show that the crystallineof chips increases to more than 60% after the solid phase polymerization, moisture content decreases to lessthan 0.000 5%, intrinsic viscosity is 1.105 d L/g. Using high viscosity polyester chips as material, the fine-ness of the product is 472 dtex, intensity is ≥7.0 c N/dtex, breaking elongation ratio is 23.7%. Because theproducts have high strength, large elongation and less fuzz, they have been used as ultrafiltration membranesupport materials in water treatment area.
